GURTIN-STRETCHER.

To at] iii/1.0772 'it may cof/mera Be it known that l, JOHN H. Villen, a citizen of the United States, residing at Fillwood City, in the county of Lawrence and State et illennsylvania, have invented certain new and useful lni] n' ireiiie1its in Curtain-Stretchers, of which the following is a specification, reference being had to the aeeoinpanying drawings.

This invention relates to new and usetul improvements in curtain st 1etehers and has for its objectto provide a novel curtain stretching traine upon which lace curtains, draperies and fabrics can be mounted for bleaching dr. lng and repairing.

Another object of the invention is to provide a curtain stretching frame which can loe quickly folded up so as to occupj,7 a very small space when not in use and can be readily set up and securely clamped when it is desired to use the saine.

A iturther object of the intention is to provide a device of this character which will possess advantages in points of etliciency and durability, is inexpensive et manufacture and at the saine tinie is sirnple in construct-ion and operation.

llllith the above and other objects in view, the invention consists in the novel features ot construction and the combination ano arrangement of parts hereinafter more fully described, pointed out iu the claims and shown in the accompanying drawings, in which,

Figure l is a top plan view showing the stretcher set up ready for use; Fig. 2 is a plan view showing the salue partially told ed; Fig. 3 is a side elevation showing the traine itolded; Fig. 4i is a detail perspective view ot one et the clamping members; Fig. 5 is a sectional view on the line of l? l; Fig. 6 is a. sectional view on the line 6 5 of Fig. 3; and Fig. 7 is a perspective view ot one pair of the sliding blocks.

Referring niore particularly to the drawings, l indicates the sectional side bars and 2 indicates the sectional end bars. he seetional side bars l are connected by means of the hinges 3, and the end bars are connected by the hinges 4C. Said side bars being hinged to allow the inner ends of the sections to fold inwardly, and the end bars are hinged to allow the inner ends of the seetions to fold downwardly. rlhe side bars l and the end bars 2 are provided on one side thereof with the grooves 5, having the under out side walls 6. Sliding block members 'l' Specification of Letters Patent.

Iare provided and adapted to' be disposed within said grooves, said blocks being provided with the side 'flanges 8 adapted to slide in the undercut side walls (5. rlwo of these bloelis are irovided at each corner of `the frame, one slidably mounted in the end bars, and one slidably mounted in the side bars, the two blocks in each corner otl the traine being pivotally secured together by means of the pivot pin 9. Headed stop pins l0 are arranged in the outer ends ot tbe grooves 5 to prevent the blocks 7 from sliding all the way out.

Clamping iiienibers ll are provided and adapted to engage the frame at each corner and clamp the bars against sliding moveniont. These clampingmembers are stamped troni sheet metal or other suitable material into the substantially rectangular plates lf2 which are bent at right angles and provided with the recesses 13 to forni the spaced arms llt. These arms le are to be disposed upon the upper and lo-wer sides ot the bars l and 2.

Cani members are pivotally mounted on the arms la and adapted to engage in the recess 16 formed in one end ot the sliding blocks 7 to hold the bars against sliding movement. These cam members l5 are arranged on the plates l2 so that one Cain engages the blocks carried by the side bars and the other cam engages the blocks carried by the end bars. Hooks l? are secured'in the inner edge et the bars l and Q whereby the curtain or other fabric can be easily secured to the traine. lt will be obvious that this traine can be readily adjusted to various sizes of curtains and other fabrics which may be readily secured to the traine. ln folding the traine., the end pieces are folded so that the side bars lie parallel and the end nieces are then folded in between the side bars, the side bars are then tolded so that the traine will be entirely folded as shown in Fig. To untold the traine and set the saine up ready ttor use the operation of folding is reversed.

From the above description taken in connection with the accompanying drawings, it will be seen that l have provided a simple and etlicient trame which is Vinexpensive of manufact-ure and at the saine time is simple in construction and operation. i

lVhile l have shown and described the preferred torni of iny invention, it will be obvious that various changes in the details oit Construct-ion and in t-he proportions may be resorted to Jfor successfully carrying my invention into practice Without sacrificing any et' the novel features or departing from the scope thereof.

Having thus described this invention,\vhat is claimed is l. n a device of the character described, the combination of a frame comprising side and end bars pivotally connected and adapted for longitudinal and lateral movement, clamping members adapted to be applied to said bars to hold the same against movement, said clamping members each comprising a substantially rectangular plate bent at right angles and provided with recesses, spaced arms formed by said recesses adapted to be disposed upon each side orn the bars, and cam members pivotally connected to said arms and adapted to engage with the bars to hold the same against movement.
